Question

@abb0t @chmvijay @aaronq  can you help me?

amtran_bus · Answer

I know that stronger reactants and weaker products mean it is endothermic.

abb0t · Answer

Well, you should know the basic ones, for instance, making a bond requires energy, while breaking bonds releases. Do you follow me.

amtran_bus · Answer

Yes.

abb0t · Answer

So, that should help you with about 50% of those.

amtran_bus · Answer

Let me be sure I do.  For example, A2+B2--->2AB.  It has a strong bond strength, right? and It yields a strong bond?

abb0t · Answer

Yes, therefore it may be safe to assume that it requires much energy.

amtran_bus · Answer

Ok. Thanks.

amtran_bus · Answer

Well, I guess I just don't get it. Sorry I said I thought I did. I have missed it 3 times.

abb0t · Answer

Lol.

Find $\Delta$H for your bonds.

amtran_bus · Answer

Delta H? Change in enthalpy? Um...ok.
